style="text-indent:25px">判斷臺車爐廢熱同收的經(jīng)濟性時可考察空氣預熱器的熱端溫差，即煙氣入口溫度和空氣出口溢度之差，因為空氣預熱器總是逆流布置的。這個熱端溫差是空氣預熱器中的較小傳熱溫差、一般應控制于50~70℃。當金屬和能源價格之比增大時上述較小傳熱溫差可選用得大一些。有時也可排煙廢熱通過管式換熱器或燕發(fā)器來加熱鍋爐給水或獲得蒸汽以制備潔凈凝結(jié)水。這時較小傳熱溫差出現(xiàn)于換熱器冷端或蒸發(fā)器的煙氣出口端。它應在70~90℃的范圍內(nèi)選月。在設計這些換熱器或空氣預熱器時還應考慮排煙中氧化硫可能引起的低溫腐蝕。這種腐蝕在受熱面壁溫略低于煙氣中的硫酸**時較為嚴重，出現(xiàn)較大腐蝕速度。如能優(yōu)化布置，使壁溫避開這較大腐蝕速度，就能減輕腐蝕。江蘇節(jié)能臺車爐哪家好臺車爐使用注意事項：傳動軸套處必須經(jīng)常檢查添加潤滑油，以防因缺油而損傷軸套。</p><div

style="text-indent:25px">臺車爐高爐爐身段開有大量用于安裝冷卻壁的孔洞生產(chǎn)工況中，高爐爐身段開有大量用于安裝冷卻壁的孔洞，其存在很大程度的削弱了爐身段的剛度。基于本文主題建立局部模型，考慮施加底部約束時，豎向和環(huán)向固定約束，徑向先施加下部爐身段開孔率為30%的線性變化位移約束(開孔率是爐身各段所有開孔面積與相應爐身段爐殼面積之比)。本文通過建立爐身段不同開孔率的下部約束模型，觀察其對上部爐頂封罩開孔受力性能的影響大小，然后予以比對。通過對臺車爐高爐爐身段不同開孔率時進行AN-SYS建模，進行了線彈性及非線性彈塑性有限元計算分析。得出如下結(jié)論: (1)標準荷載下，模擬條件的爐身各開孔率均使爐頂封罩孔洞周邊處于彈性狀態(tài)。 (2)將爐身段30%開孔率時產(chǎn)生的底部徑向位移線性化處理后作為爐頂封罩局部模型的徑向邊界約束，在標準荷載下模擬爐頂封罩的受力性能是完全可行的。江蘇節(jié)能臺車爐哪家好</p></p><br /><p>文章來源地址:
